Adjustable golf club

ABSTRACT

This club&#39;s design provides the ability to change the blade&#39;s alignment with the hosel and shaft without any loosening or disassembly of the club&#39;s parts. The blade is placed and kept firmly in its various positions through the use of spring loaded “pins”. A similar provision is made for changing the length of the club shaft: it will be “pinned” in an appropriate length, matching the position of the blade.

SUMMARY

This invention allows a golf club to be modified in both its blade setting and shaft length without loosening or disassemble, rearrangement and reassembly of its parts.

FIG. 1—illustrates the blade's parts and its connection to the hosel, which connects the blade unit to the club's shaft.

Part 2 which nests in Part 1, provides positioning holes that allow the club's blade to be fixed in various positions from vertical.

Parts 6 & 7 are the values of the blade; Part 7 shows the location of the parts to be enclosed in the club blade.

Part 3 is an axle. The blade rotates about it but cannot move along it.

Part 4 is spring loaded to keep it fixed in one of the positioning holes of the hosel. It can be taken out of position by moving the side bar manually. The side bar is to extend through an opening in the rear of the club blade so it can be moved readily. Two Part 4 units are to be employed.

Part 5 is a travel limiting pin which fits between the hosel and blade units.

FIG. 2—cutaway view of the club head's assembly

The upper Part 4 assembly is shown inserted in Part 2, holding the blade in position. If it is held withdrawn, and the blade turned, the lower Part 4 unit will automatically snap into the next position. If both Part 4 units are withdrawn, the blade can be turned into any of its positions.

The entire assembly is held together by being mounted on the axle and held in place by a screw at the end of the axle. Screws holding the blade values together are not shown.

FIG. 3—cutaway view of the grip and shaft assembly

Part 1 is the grip. It provides space for the insertion to various depths of the club shaft, effectively lengthening or shortening the length of the shaft.

Part 2 is a lever which holds the club shaft in a fixed position in the grip.

Part 3 is a leaf spring holding the Part 2 lever in position. Pressing on the upper end of the Part 2 lever releases the club shaft so it can be moved.

Part 4 shows various points on the club shaft which provide for various shaft lengths.

Part 5 shows he exterior of the housing of the positioning lever.
